Given numbers are 637, 689, 39, 313

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(637, 689) = 33761

GCD(637, 689) = ( 637 x 689 ) / 33761

= 637 / 689

= 637

Step2:

LCM(13, 39) = 39

GCD(13, 39) = ( 13 x 39 ) / 39

= 13 / 39

= 13

Step3:

LCM(13, 313) = 4069

GCD(13, 313) = ( 13 x 313 ) / 4069

= 13 / 313

= 13

So, Greatest Common Divisor of 637, 689, 39, 313 is 1
